Abstract: The invention herein is an ejection mechanism for a computer expansion card. Specifically it is for a 2-stage ejection mechanism for the expansion card that inserts in the computer. The ejection mechanism includes a body, push lever, triggering rod, etc. The push lever is made up of the travel and swinging controllers for the travel guide and swinging guide channels of the body. With the coordinated actions of the components, the push lever remains flush or is hidden within the computer housing under normal circumstances. When the user wishes to eject the card, the push lever head may be actuated to protrude from the computer housing to ease the operation of the ejection, hence the 2-stage ejection mechanism and its consequent uniqueness.
